load mulpitle objects .babylon to scene with heightmap, skybox etc

[Mira]

gryff, thank you for your work!

Yep, I know that this model is not good and export from skp->3ds->babylon just get it worse. 

Another models is loading okay, but they are have much more simple structure. 

 

Can you help me with second question? How to load mesh into the scene with their own texture? I wrote what I had change names of the textures in Blender but it doesnt work and all mesh which have been imported by ImportMesh have the textures of first loaded scene .

[Wingnut]

If I may try to clarify the 2nd question, Mira, you imported mesh into Blender... using its ImportMesh option, then you renamed the textures that were on those mesh, but the textures stayed the same?

 

I think that is normal.  I think you have to somehow remove the textures from the imported mesh, and then apply new textures (with any name you choose).  An imported mesh that has textures applied... will likely keep those textures even if they are renamed.  Likely you need to remove the textures from the imported mesh, and then apply new textures... with Blender.

 

But I am not a Blender user... so I am guessing.  Modeling is lots of work, yes?  Importing and exporting is even more work.  Importing from Google Sketchpad... directly into Blender, without having to use 3DS... would be better, if possible.  Using ONLY Blender would probably be the best, but I understand that Google has many nice models for Sketchpad.

 

And thanks Gryff, and anyone else who is working with Mira's experiments.  Mira, I hope the teacher realizes that you are trying things that are not easy at all, and you are experiencing the same problems with importing and exporting... that experts also have.  Each modeling software handles their meshes/models differently, and there is not much cooperating... it seems.  I think you will find that babylon.js will work very nicely... once the modeling is fixed... if it can be. 

 

I hope you get to play with a non-imported babylon.js BOX and GROUND someday soon, because there is lots of fun that can be had with those simple models... in babylon.js.  And particles... oh they are fun.  And physics applyImpulse... LOTS of fun.  Sprites... fun.  Shadows and animated lights and mesh... fun... and all easy.  (Easier than loading complex models after going through many imports and exports.) 

 

Stay positive.

Ok Mira an update for you. See image below - the 1K mesh babylon (in purple) loaded into scene with all the other meshes using your code.

 

Now to get that to work I did the following things:

 

1. Removed any mesh faces that had no material assigned.

2. Removed the faces for the little person. (If you want to keep that figure then it should be made a seperate object as to see it from both sides you would need to turn off backFaceCulling - no need to do that for the whole mesh.)

3. Removed all those isolated vertices.

4. Removed all the materials and textures, then assigned one simple material for the whole building - purple.

 

It loads into your scene - and does not crash my browser - so even though the mesh topology is not great it can still be loaded.

 

I have been through those materials and textures trying to see what maybe happening materials.

 

1.That mesh has 29 materials that make up one Multimaterial in the .babylon file, and those materials use 19 textures (some of which are massive in size)

2. Very few of the textures are "Power Of Two" (POT) textures. Not sure what impact this has for WebGL and babylon.js as textures for your other models are also rarely POT.

3. Materials  _103, _104, _105, _201 seem to be the worst offenders.

4. The texture for material _201 is 2 MB in size, yet is used to texture only 6 faces that are rather insignicant (horizontal guttering on back of the building). A sheer waste of bandwidth.

 

So in a nutshell, there seem to be  big issues with the materials and textures for this mesh

 

cheers, gryff

HI to everyone again! I have a really progress with my models, but I still cant understand problem with texturing of my models. May its problem just on my notebook, can someone help me and check? Now I see all models with the same texture

Thanks in advance!

Hi Mira,

 

I watch and I board not a problem with textures.

but I noticed that all your objects does not 'name', (in BABYLON.SceneLoader.ImportMesh("??", .......)) you should give name to each object (real name of the objects when you saved).

You'll have to furnish a scale your objects and can be repositioned. If all of your objects uses the same texture is that they have the same name I think.

 

 

 

[Mira]

dad72, I create a new scene in Blender now where I define names for two objects like

and load with ImportMesh to my web-page  using name of objects , but this models doesn't loadind )

May be I do smth wrong ?

https://www.dropbox.com/s/7q5inf6jlhawmm6/htdocs.rar here is my cod

[Dad72]

I'm sorry mira, I do not use blender, I don't know. I use 3ds max 2013.

 

In importMesh, need the actual name so that it loads correctly

[Mira]

dad72, name that you define in 3dsmax? I try to make analogy )

[Dad72]

 

In your ca must be fields Items but I'm not sure.

 

[Mira]

dad72, yep I did it like this way , but it still not ok

[Dad72]

I do not know how to help you more. 

[Mira]

dad72, I will try, thank you!

[Mira]

One more question: How to change position of object, which was loaded by SceneLoader.ImportMesh?

 

Is exist something like 

newMeshes[0].position = BABYLON.Vector3.Zero();newMeshes[0].position = new BABYLON.Vector3(9,9,-21);

?

[Dad72]

Yes you can do that.

[Mira]

Oh Im so sorry!)) I too much study today ) I mean SceneLoader.Load, not ImportMesh

[Dad72]

You can also

[Mira]

gryff, hello again

I know you use Blender for import/export to Babylon, so can you ask for my question again please I have created a new model and solved problems with loading, but it still doesnt work with texturing

 

https://www.dropbox.com/s/ji59k9hccgq64sx/1212.png

 

I  named model in blender

Tried load from one directory and from separate

Textures have different names

What else?

[Wingnut]

Mira, where's the link to your .rar or .zip file that contains your textures, your .blender file and your .babylon file?  Are the textures looking good when viewed/rendered in Blender, before export?  (thanks)

[Mira]

 https://www.dropbox.com/s/bjmoydrc7rgthge/loadingsc.rar - here is my scene

https://www.dropbox.com/s/x87ph1vhmkve4r3/blen.rar - here is blend files

 

Yep, all is looking good,  but I cant understand what the problem with textures

[Mira]

"Valid manifest file not found. Scene & textures will be loaded directly from the web server." I have this kind of mistake when I import meshes. Can it be a reason for my problem with texture?

[Dad72]

Hi Mira,

 

No, it has no consequence, it's just a cache management and this file is not required.

 

Your problem is either a the export of the models, or improper use of the code.

 

Can be in us showing the part of code that loads your models, you will get more help.

Yep, all is looking good,  but I cant understand what the problem with textures

here is my code and blend files

 

I use ImportMesh function like

BABYLON.SceneLoader.Load("mesh/3/", "3.babylon", engine, function (newScene) {BABYLON.SceneLoader.ImportMesh("tulpan", "mesh/tulpan/", "tulpan.babylon", newScene, function (newMeshes) {newMeshes[0].position = BABYLON.Vector3.Zero();newMeshes[0].position = new BABYLON.Vector3(-6,6,15);newMeshes[0].scaling.x = 0.1;newMeshes[0].scaling.y = 0.1;newMeshes[0].scaling.z = 0.1;             });     BABYLON.SceneLoader.ImportMesh("dfk", "mesh/dfk/", "dfk.babylon", newScene, function (newMeshes) {newMeshes[0].position = BABYLON.Vector3.Zero();newMeshes[0].position = new BABYLON.Vector3(14.5,9,-24.5);             });  

[Dad72]

Check with console.log (newMeshes) data (You will see the materials that the object uses.)

[Mira]

dad72

yep,l checked, meshes have right ID but they have used texture from scene whose that loaded first

[Mira]

how I can fix it?
